WebHow is a nerve impulse transmitted from one neuron to another? When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. ... The binding allows the nerve impulse to travel through the receiving neuron. WebIn a chemical synapse, a nerve impulse can travel in only one direction. In contrast, in an electrical synapse, the impulse travels in both directions. Also, across a chemical synapse, the impulse is transmitted with a 0.5-millisecond delay, while across an electrical synapse, the delay is almost non-existent. md red cross

WebTransmission Across a Synapse - Key takeaways. Synaptic transmission is the communication of one neurone with another neurone or cell. Synaptic transmission can act inhibitory or excitatory on the postsynaptic cell depending on the neurotransmitter.
